ELEVATING PLUMBING-BASE.

SPECIFICATION forming part. of Letters Patent No. 393,403, datedNovember 2'7, 1888.

Application filed December 5, 1887. Serial No. 257,003. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK SNYDER, of Lancaster, in the county ofLancaster and State of Pennsylvania, have invented certain new anduseful Improvements in Elevating Plumbing-Bases; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to plumbing-blocks of the kind in which an upperpart is vertically adjusted by screw-threads with respect to a lowerpart on which it fits. Heretofore these devices have not adequatelyprovided for any other adjustment besides that in a vertical direction.

The object of my present improvement is to remedy this defect,andconsequently lessen the strain on the screw-threads. To eifect this, Iprovide the vertically-adjustable upper part with anupwardly-extendingjournal-pin, and combine therewith a disk or platformhaving a downwardly-extending tubular boss, which is sleeved looselyabout said journal pin and allows the disk or platform to rock, to allowthe support or article mounted on said platform to maintain its top in ahorizontal position, notwithstanding any slight inclination of the partsA and B.

Figure 1 represents a perspective view of the base complete, showing thefoot of a stove resting on the circular disk; Fig. 2, a longitudinalsectional elevation of Fig. 1, showing the construction and adaptationof the several combined parts to each other; Fig. 3, a side elevation ofthe spanner-wrench,by which the central cylinder is rotated around theinverted cupbase.

In Fig. 2, A represents the inverted cupbase. In the center of its topis an opening, a, which is tapped to receive the threaded stud a. Thisstud is rigidly attached to the under side of the head B of theinclosing-cylinder B. Such being the case, it is obvious that if saidcylinder B is revolved to the right or left it will cause the stud a toscrew in or out of the base A at a, thus providing the central cylinder,B, with a vertical adjustment to any de- 5o sired position on thecup-base A. The cylinder B may be provided with a set-screw, b, to

lock said cylinder in position on the base A when onee adjusted; also,with one or more openings, 1), to receive the end 0 of thespanner-wrench O, by which the cylinder B is re U volved, which is onlynecessary for heavy objects. For light raisingsuch as stoves,&r'.'

it can be operated by hand with case. On the upper side of the head B ofsaid cylinder B rests the disk D, which is provided with a boss, a,around its central opening. This is the only portion of the disk Dintended to come in contact with the head B, its outer edge beingentirely clear of the head B, and itscentral opening fitting loosely tothe journal-pin d, which is integral with the head B. A rocking motionis thereby provided for the disk D, allowing it to adjust itself to anyunevenness of the floor or the object resting on it, which in this caseis the foot F of a stove.

Having thus described my invention,its operation is as follows,supposing the object to be raised and leveled a stove: I place one ofthe blocks, as shown in Fig. 1, under each of thefeet.Thenbymeansofthespanner-wrench c raise or lower the central cylinder, B,by revolving the same to the right or left, this op eration screwing orunscrewing the threaded stud a from the base A, as set forth. Thebefore-described rocking motion of the disk D allows theseveral combinedparts to automatically adjust themselves to any unevenness of the flooror the object resting on them, substantially as set forth.

I do not limit myself to the particular construction of the severalcombined parts as shown, as my invention involves a radical departure inthe construction and principle of operating elevating bases orplumbingblocks, the invention consisting, broadly, of a base or blockprovided with a vertical adjustment for height and an adjustment bywhich said base automatically adapts itself to any unevenness of thedoor or the object resting upon it.

I am aware that it is not new to combine a centrally-screw-threaded basewith an upper part or platform inclosing the same and having a screwwhich engages with the central screw-th reads of the base, the saidscrew being provided with arounded enlargement, which fits into acorresponding recess of said upper part or platform,and allows a certainamount of rocking motion to the latter, and to any journal and anannular boss surrounding it thing supported thereon. This constructionresting on said time and being free to rock, and combination I do notclaim; but, i Substantially as set forth.

Having thus described myinvention, what I In testimony whereof I havehereunto sub- 5 claim as new, and desire to secure by Letters scribed myname in the presence of two sub- 15 Patent, isscribing witnesses.

In combination with a fixed base, an upper FREDERICK SNYDER. partvertii-ztlly adjustable thereon and prolVit'nesses: vided on top with acentral journal-pin, and a A. F. SUENCK, 1o disk liuviug a centralopening to receive Said I I). ll. 1(ULIP.
